Product details
Overview
LTC7004EMSE#PBF from Analog Devices is a fast 60V high-side N-channel MOSFET gate driver IC with internal charge pump, enabling 100% duty cycle operation. It features 1Ω pull-down and 2.2Ω pull-up output drivers, 35ns propagation delay, and adjustable VIN overvoltage lockout (OVLO) and VCC undervoltage lockout (UVLO). It is used in automotive-grade high-side static switch applications requiring fast, robust gate control of external NMOS switches.
For engineers reviewing the LTC7004EMSE#PBF datasheet, LTC7004EMSE#PBF pinout, LTC7004EMSE#PBF application, or LTC7004EMSE#PBF equivalent, key selection considerations include its 60V TS voltage rating, thermally enhanced 10-lead MSOP package with exposed GND pad, CMOS-compatible INP input with 400mV hysteresis, and integrated BST charge pump regulation for sustained high-side drive.
Technical Context
The LTC7004EMSE#PBF implements a high-voltage level-shifting architecture with an internal charge pump that regulates BST–TS to ~12V, enabling indefinite conduction of external high-side NMOS switches. Its dual-output stage uses a 1Ω N-channel pull-down (TGDN) and 2.2Ω P-channel pull-up (TGUP), independently routed to allow slew-rate control during turn-on while preserving fast turn-off.
Protection logic includes three independent UVLO monitors: VCCUV-configurable gate-drive UVLO (3.5V–10.5V), OVLO pin-based input overvoltage lockout (1.11V–1.21V threshold), and BST–TS floating UVLO (3.1V typical). All trigger TGDN pull-to-TS action, ensuring fail-safe shutdown under fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max TS Voltage | 60V - Supports high-side switching across industrial and automotive input rails up to 48V nominal with margin. |
| TG Pull-Down RDS(ON) | 1Ω (typ) - Enables rapid MOSFET turn-off even with large gate capacitance (e.g., 1nF load in 13ns). |
| TG Pull-Up RDS(ON) | 2.2Ω (typ) - Provides strong gate-source charging while allowing external RC slew-rate control via TGUP. |
| Propagation Delay | 35ns (typ) - Ensures precise timing alignment between INP command and TG output transitions. |
| Charge Pump Output | Regulates BST–TS to 12V - Sustains gate drive for 100% duty cycle without external bootstrap diode dependency. |
| VCC Operating Range | 3.5V to 15V - Compatible with common logic supply rails and allows UVLO adjustment via VCCUV pin. |
| Operating Temp Range | –40°C to +125°C - Qualified per AEC-Q100 Grade I, suitable for under-hood automotive and industrial environments. |
Pinout & Package
Package: 10-lead plastic MSOP (MSE) with exposed thermal pad (Pin 11 = GND), θJA = 45°C/W, θJC = 10°C/W. Exposed pad must be soldered to PCB ground plane for rated thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Main supply input | Accepts 3.5V–15V; powers internal logic and charge pump; requires ≥0.1µF bypass to GND. |
| VCCUV (Pin 2) | VCC undervoltage lockout reference | Resistor-to-GND sets rising VCC UVLO threshold from 3.5V to 10.5V; open = 7.0V default. |
| GND (Pin 3 & Exposed Pad Pin 11) | Ground reference and thermal path | Common return for all circuitry; exposed pad is mandatory GND connection for thermal dissipation. |
| INP (Pin 4) | Digital input signal | CMOS-compatible (VIH = 2.0V, VIL = 1.6V, 400mV hysteresis); internal 1MΩ pull-down holds TGDN low at startup. |
| OVLO (Pin 5) | Input overvoltage detection input | Resistive divider from VIN sets lockout at 1.11V–1.21V; >1.21V pulls TGDN to TS to disable MOSFET. |
| TGDN (Pin 6) | High-current gate pull-down output | Drives external MOSFET gate to TS (high-side source); 1Ω RDS(ON) ensures fast, low-loss turn-off. |
| TGUP (Pin 7) | High-current gate pull-up output | Drives gate to BST (bootstrapped supply); 2.2Ω RDS(ON); series resistor enables adjustable turn-on slew rate. |
| TS (Pin 8) | High-side source connection | Connects to external MOSFET source; supports 0V–60V range; tolerant to –6V transient undershoot. |
| BST (Pin 9) | Bootstrapped supply output | Charged by internal pump to VTS + 12V; requires ≥0.1µF capacitor to TS for stable gate drive. |
| NC (Pin 10) | No-connect terminal | Must be left floating; no internal connection or function. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle support | Internal charge pump maintains BST–TS at 12V regardless of TS voltage, eliminating need for external bootstrap diode. |
| Adjustable turn-on slew rate | TGUP output allows external series resistor to limit dV/dt on MOSFET gate, reducing EMI and inrush current. |
| Triple fault protection | Independent UVLO on VCC (via VCCUV), OVLO on VIN (via OVLO pin), and BST–TS floating UVLO (3.1V) ensure safe shutdown. |
| AEC-Q100 qualified | Grade I (–40°C to +125°C) qualification confirms reliability for automotive power distribution and body electronics. |
| Thermally enhanced MSOP | Exposed GND pad reduces θJA to 45°C/W, enabling >1W dissipation in compact layout without heatsink. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side NMOS gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5109BMM/NOPB | Fixed 12V gate drive, no internal charge pump; requires external bootstrap diode; 50ns propagation delay; no OVLO/VCCUV adjustability. | Lacks integrated protection features and adjustable lockouts; suited for cost-sensitive, non-automotive designs with fixed 12V gate bias. | Choose LM5109BMM/NOPB only if external bootstrap diode is acceptable and AEC-Q100 qualification is not required. |
| MAX15066AASA+ | Integrated high-side switch (not driver-only); 40V max VIN; no BST pin; built-in current sense and thermal shutdown; 100ns propagation delay. | Replaces discrete MOSFET + driver with monolithic solution; limited to lower voltage rails and lacks slew-rate control. | Choose MAX15066AASA+ when system-level integration (current monitoring, thermal protection) outweighs need for 60V TS rating and gate drive flexibility. |
Compared with LM5109BMM/NOPB and MAX15066AASA+, the LTC7004EMSE#PBF uniquely combines 60V TS tolerance, internal charge pump for true 100% duty cycle, AEC-Q100 qualification, and fully adjustable protection thresholds-making it optimal for automotive and industrial high-reliability high-side switching where gate drive autonomy and fault coverage are critical.

FAQ
What is the maximum TS voltage rating for the LTC7004EMSE#PBF?
The LTC7004EMSE#PBF supports a TS voltage range of 0V to 60V, with absolute maximum rating of 65V. This enables direct use in 48V automotive and industrial systems with sufficient margin for transients and ringing. Operation beyond 60V violates the recommended operating conditions and may impair reliability.
Does the LTC7004EMSE#PBF require an external bootstrap diode?
No, the LTC7004EMSE#PBF does not require an external bootstrap diode. Its internal charge pump actively regulates BST–TS to ~12V, sustaining gate drive for 100% duty cycle operation. An external diode is optional only for accelerated power-up or very high-frequency (>500Hz) switching where charge pump current (~30µA) may be insufficient.
How is the VCC undervoltage lockout (UVLO) configured on the LTC7004EMSE#PBF?
The VCC UVLO threshold is set using a resistor from VCCUV (Pin 2) to GND. The internal 10µA current source develops a voltage across this resistor, which is multiplied by seven to determine the rising UVLO threshold (3.5V–10.5V range). Leaving VCCUV open defaults to 7.0V rising UVLO, with 600mV hysteresis.
Can the LTC7004EMSE#PBF drive a MOSFET with 5nF gate capacitance?
Yes, the LTC7004EMSE#PBF can drive a 5nF gate capacitance effectively. With its 1Ω pull-down and 2.2Ω pull-up drivers, it achieves 13ns rise/fall times into 1nF; extrapolating, it delivers sub-100ns transitions into 5nF. Layout optimization (short traces, proper BST decoupling) is essential to maintain performance at higher Ciss.
Is the LTC7004EMSE#PBF pin-compatible with other members of the LTC700x family?
No, the LTC7004EMSE#PBF is not pin-compatible with LTC7000/LTC7001/LTC7003. While sharing functional similarities, pin assignments differ significantly-for example, LTC7003 places OVLO on Pin 6 and TGDN on Pin 8, whereas LTC7004EMSE#PBF assigns OVLO to Pin 5 and TGDN to Pin 6. PCB layout must be specific to LTC7004EMSE#PBF.
